Yes, you can get eSIM anywhere anytime as long as you have a compatible and unlocked device.
To confirm the list of supported device models, please visit our website, accessible here.
To check if your device is locked or unlocked, please follow the brand-specific instructions for your phone:

For Apple Devices

01. Go to [Settings] – [General] – [About] and scroll down.
02. If you see “Network Provider Lock – No SIM restrictions” and “Digital SIM – IMEI (number will appear),” your phone is compatible with eSIM.
03. If “SIM restrictions” are displayed, your phone does not support eSIM.

For Samsung & Google Devices

01. Go to [Settings] – [Connections] – [Mobile networks].
02. Select [Networks operators]
03. If you see multiple available networks, your phone is likely unlocked and eSIM-compatible.
04. If only one result is displayed, or the option to search for networks is unavailable, your phone might be carrier-locked. In this case, you’ll need to contact your domestic carrier to unlock your phone before using an eSIM.

While you have the flexibility to purchase the eSIM at any time, we strongly advise acquiring and activating it before your journey. This ensures you have a reliable Wi-Fi connection, which is essential for a seamless setup. The validity of nationwide, city, and global plans commences when the eSIM is connected to the local network, while the eSIM Korea Fixed plan’s validity begins upon activation.

When it comes to selecting the right eSIM package for your trip in Korea, it’s essential to consider factors like your data needs, coverage, and the duration of your stay. Here are a few options to keep in mind:

| eSIM Korea Unlimited Plans: These plans offer unlimited data, with reduced speeds (384 kbps) after you’ve used up your high-speed 4G LTE data. Validities range from 3 to 30 days.

| eSIM Korea Fixed Plans: This plan ensures consistent 4G LTE connectivity with a data allowance of 6GB for 10 days.

| eSIM City Plans: Ideal for travelers staying in a specific city for an extended period.

Prior to making your selection, we strongly recommend thoroughly reviewing the details and terms of each eSIM plan. If you require personalized assistance in choosing the perfect plan, don’t hesitate to reach out to the eSIM World team at [email protected].

Unfortunately, eSIM Korea offers data-only plans, which means local phone numbers are not part of these packages. Consequently, these eSIM plans do not support the ability to make voice calls or send SMS. If you require voice calls and SMS capabilities, we suggest using VoIP (Voice over Internet Protocol) services like Skype or other messaging applications that rely on data connectivity to enable calls and messaging.

Once your payment is completed, our eSIM QR code is automatically sent to the provided email address within 15 minutes. If you haven’t received it within this timeframe, please follow these steps:

1. Check Spam or Promotion Folders
Look in your spam or promotion folder, as your email may have been filtered there.

2. Email Address Accuracy
If there’s a typo in your email address, kindly reach out to us at [email protected]. for a prompt resend.

3. Email Linked to Payment
The QR code is sent to the email associated with your payment method. Please check that inbox as well.

If you continue to experience issues, please reach out to our 24/7 customer support.

If you’re unable to access data after successfully activating the eSIM plan, please ensure that [Data Roaming] is turned on and try restarting your phone. If you’ve installed an eSIM plan that allows for manual APN (Access Point Name) settings, please follow the instructions provided to enter the APN information into your device manually. You’ll receive the APN information once you receive an instruction after payment.

To confirm your eSIM activation, look out for these two indicators:

| eSIM Profiles
Visit your device’s eSIM settings, where you’ll find a list of available profiles or plans. When your eSIM is successfully activated, you’ll see an active profile without a phone number listed among the options.

| Signal and Connectivity
Once your eSIM is activated and connected to a cellular network, you should notice signal bars or connectivity indicators in your device’s status bar. You might also see the carrier name associated with the eSIM, confirming both its activation and network connection.

It’s highly recommended to deactivate your original SIM to prevent incurring data roaming charges from your domestic carrier while using the eSIM.

However, if you still want to receive calls and SMS on your home number while using the eSIM, you can keep your original SIM active. In this case, we suggest disabling the “Automatic Cellular Data Switching” feature on your device to prevent unintended data usage, ensuring that data traffic is directed through the eSIM plan rather than the original SIM.

You can easily estimate your data usage by accessing your device’s Settings. For precise data consumption details, please contact us at [email protected].
